Effect of Refinement Process Condition and Sintering Property on the Low Melting Point Glass Powder by High-pressure Homogenization Technology

Using carboxymethyl cellulose(CMC) as an anti-settling agent of low melting point glass powder aqueous dispersion,the high-pressure homogenizer can refine glass powder particle to reduce their size.Different high-pressure homogenized time affected on glass powder’s particle size and the sintering property.Under the same pressure(50 MPa) a longer high-homogeneous time gets smaller particle size and narrows particle size distribution.And the softening temperature and sintering temperature are also lower.The results show that the high-pressure homogenizer techniques can be used to reduce the particle size of the glass powder,so that the softening temperature and sintering temperature will be lowered.
